So many people turned out for the Women's March in Chicago that organizers have canceled their plans to march through the city's downtown.

The group in Phoenix said their slant wasn't on bashing Trump but more about creating unity and solidarity.

Still, there were still plenty of anti-Trump signs. Many of those taking part were concerned about Trump's agenda.

"I feel a lot of threats to our choice over our bodies," one Phoenix marcher said. "I see a threat to the environment. I certainly see a threat over public education and without education we all lose."

One of the coordinators of the local march said they were they to give voice to some of the concerns they feel aren't be appropriately represented by the new administration.

"It's important to make sure that we're representing racial, social, economic and environmental justice in a way that's meaningful and in a way that can be heard," she said.

Another marcher explained why she showed up.

"The reason I'm here is because we're already great," she said. "We don't need to make America great, we're already great with supporting each other no matter what our beliefs."

Elsewhere, there were signs that the crowds in Washington could top those that turned out for Trump's inauguration on Friday.

City officials said organizers of the Women's March on Washington more than doubled their original turnout estimate to 500,000.The rallies were a peaceful counterpoint to the window-smashing unrest that unfolded on Friday when self-described anarchists tried to disrupt the inauguration. Police used pepper spray and stun grenades against demonstrators. More than 200 people were arrested.
